They nerfed the exp required to level. Just queue for dungeons and do the quest lines leaving each zone as you level up. Simple as that.

Not exactly sure what you're going on about there as experience from PVP was nerfed heavily back in Cataclysm. As far as catching up gear-wise, go to the Timeless Isle when you reach 90. The creatures there drop tokens that turn into 496 gear and "Burden of Eternities" that turn those tokens into 535s instead. The previous LFR tier is still 502s and the new LFR will only open the first four bosses for 528 gear, if you're lucky enough to actually get any gear at all from them.

As soon as u out level a zone... leave it! Unlike lower levels you'd sometimes stick it out a few green quests but the difference in exp rewards from quests is so big in mop you're gimping yourself if u stay in a zone.
Should look something like this..
85-86: jade forest
86-87: four winds
87-88; kunlai or krasarang
88-89 townlong
89-90: dread wastes (this place looks shit and desolate but hands down best quests for lore. Very involving)

monkey lvling was the old best thing if u had a friend. small turtles giving 45k would be ideal as well.. thers tons of them around and 90s only want big or elite ones for timeless coins.. so i guess timeless isle is the new exp farm atm.
